I'm currently running 06 headlights with 6000k bulbs on my 04 coupe. About a week ago I noticed that my right side headlight was a lot blue-er than the other, and that it was never like this. Yesterday I noticed that it wasnt working anymore. I played around with it and found out that when I first turn on the headlights the right side stays on for about 10 seconds, flickers, then turns off. What could be causing this problem? Bulb? Ballast? Any help is greatly appreciated.

 

I would try swapping bulbs to see if the bulb is the problem. If at that point, it is still acting up, I would try swapping out ballasts. Seems like it would be the bulb.

 

Your bulb is dead. Just put your stock bulbs back in and you'll be fine. Happend to me too.
